VPP
90
Input
VPP—This pin should be left unconnected as an open circuit for normal
functionality.
EXTAL
59
Input
External Crystal Oscillator Input—This input should be connected to a
4MHz external crystal or ceramic resonator. For more information, please refer
This pin can also be connected to an external clock source. For more
information, please refer to Section 3.6.3.
XTAL
(CLOCKIN)
60
Output
Input
Crystal Oscillator Output—This output connects the internal crystal oscillator
output to an external crystal or ceramic resonator. If an external clock source
over 4MHz is used, XTAL must be used as the input and EXTAL connected to
VSS. For more information, please refer to Section 3.6.3.
External Clock Input—This input should be used when using an external
clock or ceramic resonator.
CLKO
57
Output
Clock Output—This pin outputs a buffered clock signal. By programming the
CLKO Select Register (CLKOSR), the user can select between outputting a
version of the signal applied to XTAL and a version of the device master clock
at the output of the PLL. The clock frequency on this pin can be disabled by
programming the CLKO Select Register (CLKOSR).
